DISPLAY DEVICE.

This invention relates to a novel advertising display device and more particularly to a device for displaying a thin film of viscous liquid, such for example, as motor or lubricating oil.

Itis an object of the invention to rovide a device for displaying viscous liqui such as motor or lubricating oil, in the form of a continuously flowing, broad and unbroken film, in order to visibly demonstrate the body and color of the liquid.

Another. object of the invention is to provide an advertising display device, wherein the liquid being displayed is recirculated continuously, so that the display may be continued indefinitely with a given quantity of li uid. y

Sti l another object of the invention is to provide converging guides between which a lilm of liquid is maintained.

Av further object of the invention is to provide means for circulating the liquid through the device, and means for regulating the flow of liquid therethrough.

Other and incidental objects, advantages and features of the invention will readily appear, as the following description, taken in connection with the accompanying drawings, proceeds.

In the drawings, Figure 1 is a View in front elevation of an advertising display device embodying the features of my invention.

Fi re 2 is a view in end elevation, partially 1n section, of the apparatus shown in Figure 1, and y Figure 3 is an enlarged sectional view of the oil supply pipe, showing the manner of connecting it with the by-pass pipe.

Referring to the drawings, there is indicated generally by the numeral l0, a cabinet adapted to support the display device, and to contain at least a ortion of the operating mechanism. The cab portion 11 and an upright portion 12, disposed at the rear of the table.

Concealed from view, within the cabinet and below the table 11, there is a reservoir or sump 13 adapted to contain the viscous fluid used in the demonstration. A cylindrical strainer 14 is positioned withinthe sump 13,

inet consists of a table and into the strainer there extends an end of a suction pipe 15, the opposite end of which leads to the suction side of a ump 16, 'which is operated by a motor 17, t e pump and motor being, mounted upon a support 30 55 which rests upon halves of sponge rubber balls 31 to eliminate vibration noises. A sup ly pipe 18 connects at one end with the disc arge or pressure sidel of the pump 16 and extends upwardly through the u ri ht 6o portion of the cabinet for a considerable istance. The upper end of the supply pipe is bent to form an inverted U and depends int-o a substantially horizontally disposed rece tacle or spout 19 which projects through t e o5 front wall ofl the upright portion of the cabinet. Turn-buckles 2O secured at one end to the rear of the spout 19, and at the other end to the back of the cabinet, are provided so that the position of the spout may be suitably adjusted as required.

A receiving receptacle or container 21, which is formed with a false bottom, is suitably mounted on the table 1l, directly over an. opening which is provided in the latter. The receptacle is provided with a truncated, substantially conical lining 22, which extend -downwardly and projects for a short disof the reservoir 13, so that anv liquid discharge into the receptacle will gravitate to the reservoir, without any danger of splashing or the loss of any of the liquid.

The forward end of the spout 19 is formed with a horizontally disposed lip 24, to each of the opposite ends "of which there is soldered or otherwise secured an end of a filament, preferably in the form of a brass wire 25. The two wires depend from the lip, extending downwardly through the open end of the receptacle 21, and into the splash guard 23, where they are' suitably drawn and fastened together. The extreme lower ends of the wires are secured to a weight 26 which is thereby suspended within the splash guard so as to maintain the wires taut.

A byfpass pipe 27 having a valve 28 con- 100 nects at one end with the supplyl pipe 18, while its opposite end extends into the reservoir 13, so that a portion of the liquid pum ed through the sup ly line may be returne to the reservoir befbre ever reaching the spout 19. A valve preferably in the form of a needle'valve 29 is positioned in the supply line 18 for controlling the flow of liquid through the'line. By a proper manipulation of the valves 28 and 29 the quantity of liquid finally delivered to the spout 19vmay be easily controlled and regulated.

The connection between the by-pass line 27 and the supply pipe 18 is as siown in section .in Figure 3. It will be seen that the by-pass pipe extends a short distance into the supply pipe and that it is formed with a beveled lip 32 on its upper side to insure the'certain-by-passing of the liquid when the valve 28 is opened.

It will be seen that a regulated supply of liquid is continuously pumped to the spout 19, the level of the liquid therein gradually rising until it begins to flow over the edge of the lip 24. As the viscous liquid passes over the lip it contacts with the two filaments or wires 25, the upper ends of which are spaced somewhat apart, and because of the viscosity of the liquid, it clings to the wires and forms a thin film between them, raduall flowing downward toward the point at w ich the wires converge. A baille or bubble skimmer 33 is mounted between the opposite sides of the spout, with its lower edge at a sufiicient height above the bottom of the spout to skim such air bubbles as may by chance be present in the li uid as it passes slowl beneath the bafiie.

qWhen the liquid has escended the entire length of the wires, it gravitates into the reservoir 13, from which it may again be drawn by\ the suction of the pump 16 to be again recycled through the system. Thus a given quantity of llquid may be used in maintaining a continuous flow through the apparatus., The thin film of liquid spread,

between the two suspended wires renders certain characteristics of the liquid visible to the eye, so that its colorpmay be readily observed and its body demonstrated by the broad unbroken film maintained between the wires.

Apparatus of preferred form and construction has been illustrated and described for the purpose of showing a way in which this invention may be practiced, but the inventive thought upon which the invention is based is broader than this illustrative embodiment thereof and no limitations are intended other than those imposed by the appended claims.
